Couple accused of plotting a bomb attack at 'Westfield' to coincide with the tenth anniversary of 7/7 'made a video of a test run explosion in their back garden'Mohammed Rehman filmed himself trying home made bomb in his garden
Hoped he could then 'upscale' to cause multiple fatalities, jurors heard
He is jointly charged with his secret wife for preparing for a terrorist attack
He was arrested when he asked his Twitter followers which London landmark he should target under the account called 'Silent Bomber'
This video shows the chilling moment a would-be suicide bomber allegedly tested deadly explosives for an attack on London.
Mohammed Rehman, 25, who referred to himself as the 'Silent Bomber', filmed himself trying out the home-made bomb in his back garden.
He hoped he could then 'up-scale' to cause multiple fatalities, jurors heard.
He allegedly carried out at least two such tests and sent footage to his secret wife Sana Ahmed Khan who funded the purchase of ingredients for a bomb on eBay, the court heard.
The video was shown during the Old Bailey trial of the couple who are jointly charged with preparing for a terrorist attack on or around May 28 this year.
In the video, voices chant 'Allahu Akbar Bismillah [God is great, in the name of God]' while someone can be heard saying 's*** man.'
There was then a loud bang and a puff of smoke while someone shouts out 'f****** hell' before the footage ends.
Rehman had also allegedly boasted to his wife of conducting a test explosion in a public park.
He messaged her saying: 'Plannin on just going n testin that thing baby at the park darling but its FREEZIN.'
Jihadi-John style- hunting knife
The prosecution has said Rehman was 'intent on martyrdom' when he tweeted: 'Now I just make explosives in preparation for kuffar lol and when I've made the required amount I'll be wearing them on my chest.'
He had also trawled the internet for subjects including 'suicide bomber history', 'dying for god' and '9/11'.
Counter-terrorism officers were alerted after Rehman, whose Twitter profile picture was of Mohammed Emwazi, asked his followers for advice on which of the two targets to hit - London Underground or Westfield shopping centre, jurors were told.
On the day of the tweet, he had repeatedly trawled YouTube for material about the London bombings ahead of the 10th anniversary.
Rehman also tweeted a link to the al-Qaeda uncensored media release about the 7/7 bombings, the court heard.
Before police swooped on his Reading home, he allegedly said he had rigged up a bomb which could be triggered at the touch of a button at his bedside, saying: 'Nobody gets in the way of my Jihad.'
What officers actually found were a hunting knife commonly used by Emwazi known as 'Jihadi John' and dangerous chemicals for a massive bomb which was just days away from being completed. They have been shown to the jury.
A diagram was found showing how to make a home-made detonator using a mobile phone, a 9v battery and a fairy light.
Equipment to prepare for the attack
Periodic Table
Dangerous chemicals were being prepared for a massive bomb, which was just days away from completionOfficers seized more than 10kg of urea nitrate - a highly explosive chemical - which if detonated 'would have caused multiple fatalities in a public place', prosecutor Tony Badenoch QC said.
He told jurors: 'The evidence suggests that the London Underground may well have been on his mind as a potential target as he was particularly fixated with the events of 7/7 and he referred to Shehzad Tanweer, one of the 7/7 suicide bombers, as his "beloved predecessor".
'[He is] a highly dangerous individual who had demonstrated the capability to explode a bomb and vocalised an extreme anti-Western message.'
On July 7 2005, 52 people lost their lives and more than 770 were injured.
Rehman, 25, of Reading, and Khan, 24, also of Reading, deny preparing terrorist acts on or before May 28 this year.
The couple married on October 31, 2013 but lived separately.
Rehman has also pleaded not guilty to a charge of possessing an article for terrorist purposes.
